Abstract

Patente de Invenção: <B>"MISTURA DE POLìMERO RADIOPACO"<D>. Um implante médico tal como um cateter, uma sonda, um enxerto vascular ou outro implante, compreendido de uma mistura de dois polímeros. Em uma concretização, o primeiro polímero inclui um diisocianato, um poliol e um primeiro extensor de cadeia tendo uma concentração de bromo superior a cerca de 30 por cento. O segundo polímero compreende um diisocianato, um poliol e um segundo extensor de cadeia tendo uma concentração de bromo superior a cerca de 10 por cento.Invention Patent: <B> "RADIOPAQUE POLYMER MIXTURE" <D>. A medical implant such as a catheter, probe, vascular graft or other implant, comprised of a mixture of two polymers. In one embodiment, the first polymer includes a diisocyanate, a polyol and a first chain extender having a bromine concentration greater than about 30 percent. The second polymer comprises a diisocyanate, a polyol and a second chain extender having a bromine concentration greater than about 10 percent.
